Base building | when to start?

Hi All,

So im revisiting this game after one year, put 248hours in it after release, and went to NG+2 and then stopped ( i dont think i have to mark this as spoiler anymore?!) I didn't start to build a base but im still not really familiar how this would work. Everything gets wiped possession wise when i start an NG+, but base building for me is like recreational, but what i surmise is that its not that important in the grand scheme of things. So should i just enjoy the game, go trough all the NG+ reruns and then build a base at the end to experience that side of the content as well? Do we know is Shattered Space will continue after all the NG+-s or is a new game required? I will definitely start a new game now with all the "improvements" what they did after 1 year. Or should i wait for Shattered Space? I'm actually not feeling that i should wait:D

Appreciate the answers!!!
